[A/S] landline electrical

["R Berger class of 64" <camelrenter@xxxxxxxxx>]

We have a '63 22' Flying Cloud that we want to hook up to electical 
power for the first time, and start checking systems after sitting 
since a purchase a while back.  But where do we plug power into the 
Airstream?  I only found two outside connections, and both were 
female.  Am I suppose to have a double male plug powercord to go to 
landline power, and then go to one of those?  Helpless near Seattle.
